FOUNTAIN-PEN FILLER.

Application led -May 23, 1925. Serial No. 32,483.

This invention relates to fountain pens and filling mechanism thereforand has for an object to provide an improved construction wherein theusual sack is eliminated and means provided for drawing a quantlty ofink directly into the barrel.

Another object of the invention is to provide a fountain pen in which acollapsible cup is provided at'one end of the barrel of a fountain penand associated with a plunger for permitting a ready collapsing thereoffor `expelling air from the barrel of the fountain pen.

A still further object of the invention is to provide a fountain penwitha filling mechanism at the end opposite the pen, the arrangementbeing such that the filling mechanism may be operated once or severaltimes to partially fill or entirely 'fill the barrel of a pen.

. In the accompanying drawing Figure 1 is a view partly in elevation andpartly in longitudinal vertical section, the same disclosing anembodiment of the in.` vention.

Figure 2 is a view similar to the right hand half of the' showing ofFigurel 1, the same beingon an enlarged scale and the filling mechanismmoved to a collapsed position.

Figure 3 is a'transverse sectional view through Figure 1 on line 3-3,the same being on an enlarged scale.

Referring to the accompanying drawing by numerals, 1 indicates a capwhich may be of any usual construction and which isV normally slippedover one end of the barrel 2 so as to cover the pen point 3 andassociated parts when the device isV not in use. The barrel 2 is formed,l with the usual chamber 4 but in the present invention it is notnecessary to provide a bag in this chamber as the ink is drawn directlinto' the chamber and is fed therefrom 1n the usual manner as the penisused. The pen point 3 and associated parts are of any usual or preferredstructure and form no part of the present invention except in combina,-tion. l The barrel 2 at the end opposite the pen point 3 is providedwith a reduced passageway or bore 5 merging into an enlarged 1nternallythreaded chamber 6. An annular de ression 7 is also provided intowhichthe en arged annular portion or enlargement 7 3 uppermost.

of the collapsible cup 8 is mounted. If desired, the annular enlargement7 maybe cemented or otherwise rigidly secured to the barrel 2.. Anexternally threaded sleeve 9 is screwed into the chamber 6 until thelower end thereof presses the enlargement 7 tightly and firmly into theannular groove 7. The sleeve 9 is provided with an apertured end 10through which vthe rod or plunger 11 extends, said rod or plunger beingpreferably integral with` the cup 8, which cup is preferably' made froma good gra-de of rubber and which is adapted to be collapsed as shown inFigure 2 when expelling either ink or air from the chamber 4. 1

After the ink or` air has been expelled as shown in Figure 2, the en dof barrel 2 carrying the pointv 3 is submergedin ink` in case it isdesired to again ll the chamber 4 andfthen plunger 11 is released. Thiswill permit the cup 8 to gradually distend until it assumes the positionyshown in Figure 1 and as it distends it will produce a suction orrarefaction in chamber 4 and in this manner draw into this chamber aquantity of ink. As shown, the ldisplacement of cup 8 is less than thechamber 4 and if it should be desired to entirely fill chamber 4 afterthe first supply of ink has been drawn therein, the entire pen structureis moved to a vertical position with the point The plunger 11 isagaincaused to function until it assumes the position shown in Figure 2 andthis vaction will expel a given quantity of air so that an additionalsupply of ink may be drawn in as the cup'again distends. This action isrepeated several times or until the chamber 4 is completely filled. In'order that the plunger 11 may not be actuated accidentally, a-protecting cap 12 is screwed onto the outer end ofthe sleeve 9. Thiscap also acts as a flocky nut for locking the sleeve against accidentalmovement. After the chamber 4 has been filled or` partially filled,` theentire device then acts in the usual man ner ofv a fountain pen.

What I' claim is: 1. Ina fountain pen; a barrel having a reduced passageat the end opposite that car- IIU vided at its closed end with a shortrod projecting out through an aperature in the end of the chamber,whereby when the cup has been collapsed in the chamber by the.

rod and the rod released, the cup will distend to produce suction in thebarrel.

2. In a fountain pen, a barrel having a reduced passage at the endopposite that carrying the pen point and at said end an internallythreaded chamber, a collapsible and extensible rubberv cup having itsopen end secured around the said passage and prof vided at its closedend with a short rod projecting therefrom to normally lie Wholly outsideof the cup, and an externally threaded sleeve screwing into the saidchamber around the cup and having an apertured end through which the rodprojects.

3. In a fountain pen, a barrel having a reduced passage adjacent itsupper end ank annular groove around said passage, and an internallythreaded chamber at said end, a collapsible and extensible rubber cuphaving at its open end an annular exterior enlargement fitting in thegroove surrounding the passage and provided at its closed end throughwhich the rod 4 reduced passage adjacent its upper end and v aninternally threaded chamber at said end, a collapsible and extensiblerubber cap having its open end secured around the passage and providedat'its closed end with a short rod vprojecting therefrom to normally lieWholly outside of the cup, an externally threaded sleeve of a lengthgreater than the depth of the chamber and screwin into the same Withy aportion projecting t erefrom, said sleeve enclosing the cu apertured endk throu h Wh1ch the rod -pr0 jects, and an internay threaded capscrewing on the projecting end of the sleeve, said cap serving toprotect the said rod and to and having an prevent accidental movement ofthe sleeve.
